Lettuce and Tilapia Aquaponics System

Lettuce and Tilapia Aquaponics System [Simple Method]

Integration of lettuce and tilapia : The integration of Tilapia farming in intensive system and Lettuce production, called “aquaponics system” is practiced successfully growing in these countries [USA, Australia and Europe] and others. the residual water from intensive tilapia fish production provides sufficient qualitative characteristics for competitive production of lettuce without need adding commercial fertilizers.

Make money from Lettuce and Tilapia aquaponics

It’s quite possible to set up a commercial aquaponics business that is profitable from selling the Lettuce and Tilapia fish.

Many vegetables can be grown in water culture using nutrients either provided by chemical fertilizers (hydroponics) or produced by aquacultured fish.

Why Aquaponics?

Aquaponics does not require soil.

Can utilize marginal land.

Supply both vegetable and fish.

More room for local production!

89% of lettuce is imported

44% of fish is imported

The post describes an experimental setup to growing lettuce, shallow trays were constructed lined with plastic.

Lettuce plantlets were placed in small net pots inserted in holes in styrofoam panels suspended over the water by testing edges on the walls of the trays.

The lettuce roots took up nutrients in the trays from the water.

The nutrients were provided either by added chemical fertilizers or by effluent water taken from tanks in which fish were grown (plus some supplemental chemical nutrients added).

The water from the lettuce trays each time recycled to the fish tanks effluent water was added to the trays.

The only electrical component in the system was an air pump to aerate the fish tanks, providing the fish with oxygen and preventing denitrification.
